Self-locking coin lid for bottles



Feb. 20, 1934. J. A. RINGENBERG SELF LOCKING COIN LID FOR BOTTLES Filed March 18, 1930 Inventor UM Aliorney Patented Feb. 20, 1934 UNITED STATES SELF-LOCKING COIN LID FOR, BOTTLES John A. Ringenberg, Tulsa, Okla., assignor to Tom G. Boman, Grand Rapids, Mich.

Application March 18, 1930. Serial No. 436,704

5 Claims.

My invention pertains to banks and more particularly to a self locking lid or cover adapted to be attached to the ordinary milk or cream bottle.

One objection to present day coin containers is the fact that coins may be shaken out of them with more or less difiiculty. Another objection is that they are expensive to manufacture.

I overcome the first of the above objections by providing a self locking unit which cannot be removed after it has been inserted to its proper position and which also has spring flaps which prevent coins from being shaken out surreptitiously or otherwise.

The other above named objection is overcome by utilizing a milk or cream bottle as the container, this being the main element and consequently the main item of expense, and moreover such containers are readily procurable due to their common usage.

Other objects will appear or become apparent or obvious, during the description of the device shown in the accompanying drawing in which;

Figure 1 is a plan view of my device in unfolded relationship.

Figure 2 is a cross sectional view through an ordinary milk bottle showing my device partly inserted therein.

Figure 3 is a view taken along the line IIIIII of Figure 1.

Figure 4 is a cross sectional view through the neck of an ordinary milk bottle showing my self locking lid or cover in its locked position.

Figure 5 is a View taken along the line V-V of Figure 4.

Similar numerals represent throughout the several views.

As shown in Figures 2 and 3, B indicates a bottle having an interior rim D into which my improved device is adapted to seat.

As shown in Figure 1, l0 designates a disc, lid or cover having a slot 11 through which coins may be inserted. Portions 20 and 30 are connected to the disc by means of the necks 13 similar parts and 14, respectiveley. The dotted lines of Figure 1 indicate where the bends are to be made in order to construct my device.

The portion consists of an edge part 21, side parts 22 and 23, a spring lip 26, and flaps 27 and 28. The side parts 22 and 23 have sloped or tapered upper edges 24 and 25, respectively, these edges being adapted to contact with the disc as clearly shown in Figures 2 and 4. The other portion likewise is formed of an edge part 31, side parts 32 and 33, a spring lip 36, and locking lugs 37 and 38.

The operation is readily understood. After the several parts, which are preferably formed by stamping out of an integral sheet of metal, are bent to their proper positions, the two juxtaposed depending facing channel portions overlap each other as shown in Figures 2 and 3. However, when the closure or device is fully pushed down the channel portions spring apart due to pressure exerted upon the tapered edges 24, 25, 34, and 35, through the disc 10 until the locking lugs spring out and over the adjacent sides of the opposed portion and hence the device is locked into position.

It should be noted that the spring lips 26 and 36 have little or no resiliency. Their main object is to provide a means for adjustment when the device is being manufactured so as to take care of any slight error in the positioning of the locking lugs.

The flaps 2'7 and 28 extend downwardly as shown in Figure 5 and thus prevent any of the inserted coins from being removed by inverting the bank and shaking it.

Having thus revealed this invention I claim as new and desire to secure the following combinations and elements, by Letters Patent of the United States.

What I claim is:-

1. A milk bottle device comprising, a disc, having a slot therein, adapted to fit into the rim of a milk bottle, juxtaposed depending portions movably atached to the disc so as to face each other, and means to lock the portions in spaced relationship.

2. A device as set forth in claim 1 but further characterized by the fact that the sides of the portions overlap each other and also that one of the portions has a flexible side portion, a lug rigid with said flexible side portion whereby looking will occur when the portions are in spaced relation.

3. A self locking coin lid for bottles consisting of a disc having an opening therein, locking means connected to the disc, means to expand the locking means and locking lugs adapted to prevent return movement of the locking means.

4. A self locking cover for milk bottles or the like consisting of a disc having a slot therein, depending portions flexibly attached to the disc, and means adapted to lock the said portions in spaced relationship.

5. In a bottle the combination of a closure positioned on the neck of the bottle, said closure having a coin opening or the like therethrough, means depending from said closure down through said neck into the bottle, means for moving said depending means laterally whereby it abuts against the interior of the bottle and means for locking said depending means in its lateral position.
